If
you're new to programming, you may need some basic information about compilers.
This section is for you.

What is
a compiler and what does it do?

A
compiler is a program that turns C-language code into binary instructions
that your computer can understand and execute.

Many
beginning C students start out by writing a program that looks like this:

#include<stdio.h>

void
main(){

printf("Hello,
world!");

}

This
classic program (or old chestnut) displays the words "Hello,World!" on
the computer screen. If you type this into any text editor and save it
with a .c file name extension, you will create a source
file.
